Integrated gas purifying tower

Abstract

The invention relates to a gas integrated purification tower, which comprises an upper seal head, a lower seal head and a tower body, wherein the tower body is divided into an upper layer section, a middle layer section, a backwashing section and a lower layer section sequentially from the top down; a top layer screen mesh is arranged between the upper seal head and the upper layer section; a middle-upper layer section gas distributor is arranged between the upper layer section and the middle layer section; a middle-lower layer section gas distributor is arranged between the middle layer section and the backwashing section; a baffle plate is arranged between the backwashing section and the lower layer section; a lower layer section gas distributor is arranged between the lower layer section and the lower seal head; the upper ends of the upper layer section, the middle layer section and the lower layer section are provided with an upper layer section feed inlet, a middle layer section feed inlet and a lower layer section feed inlet respectively; the lower ends of the upper layer section, the middle layer section and the lower layer section are provided with an upper layer section discharge hole, a middle layer section discharge hole and a lower layer section discharge hole respectively; a spray washing pipe is arranged in the backwashing section so that a washing solution enters from a spray washing solution inlet; and the upper layer section, the middle layer section and the lower layer section are provided with different active carbons. The gas integrated purification tower can perform purification treatment on the pollution components of oxysulphide, oxynitride, hydrargyrum, dioxin and the like simultaneously.

Description

technical field [0001] The invention relates to a gas purification tower, in particular to a gas integrated purification tower for treating industrial waste gas containing complex components. Background technique [0002] At present, the purification of industrial waste gas containing complex components usually adopts a combination of multiple equipment, which separately purifies the sulfur oxides, nitrogen oxides, mercury and dioxins contained in the waste gas Not only the cost of equipment is large, but also the floor area is large. The currently used gas purification tower is only equipped with one kind of activated carbon, which usually can only purify one component in the gas, and because the exhaust gas concentration at the exhaust gas inlet of the purification tower is relatively high, after long-term use, the activated carbon near the exhaust gas inlet is relatively weak. dirty, while the activated carbon away from the exhaust inlet is relatively clean. In this way...
